The article aims to show how the main stages of Löwithian thought can be connected through reference to the theme of nature. Starting from this interpretation, it will be possible to clarify how one can speak of a pars construens
of Löwithian philosophy and understand its significance in relation to its pars destruens.  Finally, an interpretation of Löwithian naturalism will be given in relation to the theme of transcendence and suicide already present in an early form in the first autobiography written by the author Fiala. Die Geschichte einer Versuchung.
